Input: Consider Input: Eventually, radiation pressure from the star blows away the envelope and the new star begins its evolution. The properties and lifetime of the new star depend on the amount of gas that remains trapped. A star like our sun has a lifetime of about 10 billion years and is just middle-aged, with another five billion years or so left. And once the fusion reactions begin, they exert an outward pressure. As long as the inward force of gravity and the outward force generated by the fusion reactions are equal, the star remains stable. Clouds of gas are common in our galaxy and in other galaxies like ours. These clouds are called nebulae. A typical nebula is many light-years across and contains enough mass to make several thousand stars the size of our sun. The majority of the gas in nebulae consists of molecules of hydrogen and helium--but most nebulae also contain atoms of other elements, as well as some surprisingly complex organic molecules. STAR BIRTHS are started when the interstellar matter in gas clouds, such as the Eagle Nebula shown here, compresses and fuses. Irregularities in the density of the gas causes a net gravitational force that pulls the gas molecules closer together. NGC 6326, a planetary nebula with glowing wisps of outpouring gas that are lit up by a binary central star. A planetary nebula, often abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from old red giant stars late in their lives. A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin. Most planetary nebulae form at the end of the star's life, during the red giant phase, when the outer layers of the star are expelled by strong stellar winds. After most of the red giant's atmosphere is dissipated, the ultraviolet radiation of the hot luminous core, called a planetary nebula nucleus (PNN), ionizes the ejected material. A planetary nebula, abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. The word nebula is Latin for mist or cloud, and the term planetary nebula is a misnomer that originated in the 1780s with astronomer William Herschel because, when viewed through his telescope, these objects resemble the rounded shapes of planets. Herschel's name for these objects was popularly adopted and A planetary nebula, often abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from old red giant stars late in their lives.[2] The word nebula is Latin for mist or cloud, and the term planetary nebula is a misnomer that originated in the 1780s with astronomer William ... Theoretical models predict that planetary nebulae can form from main-sequence stars of between one and eight solar masses, which puts the progenitor star's age at greater than 40 million years. Although there are a few hundred known open clusters within that age range, a variety of reasons limit the chances of finding a planetary nebula within. Planetary nebula - Membership in clusters. 1  Planetary nebulae have been detected as members in four Galactic globular clusters: Messier 15, Messier 22, NGC 6441 and Palomar 6. Query: at what point does a star form from a nebula

Output: A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion.


Input: Consider Input: Medical Marijuana Facts: Cannabis May Simplify Organ Transplantation. 1  Organ transplant rejection is a serious problem that is of a frequent occurrence in medical practice. While there are various methods to stop the rejection of the transplant by the immune system, they are not applicable in each case. Hair-based drug tests are the most accurate, as the chart below shows, since traces of everything from alcohol to morphine can remain in the follicle for up to 90 days: Dragan Radovanovic/Business Insider A federal mandate requires that drug tests screen for all five of these types of drugs. Time Frame Hair drug tests can detect drugs that have been in the system for 90 days, or three months. Considerations Many consider hair testing to be much more effective than urine testing because the results cannot be as easily tampered with. The hair test can also detect drugs that have been in the system for a much longer period of time than a urine test. Fact In order for the hair test to be accurate the sample of hair used must contain 90 to 120 strands of hair. How long does marijuana stay in your system once smoked? How do you determine how long weed will stay in your system when doing a drug test or a hair folicle test I am 5'4, weighing 335 lbs hoping that helps. Hair drug testing. Hair testing may be used to determine drug use over the longer term, usually over a 90-day period of time. Hair can be tested for cocaine, marijuana, opiates, methamphetamine, phencyclidine, and alcohol. What happens during workplace drug testing? Drugs can usually be detected in the saliva for only a few hours to a few days. Hair test. Analyzing the hair for chemical traces may be the most accurate way to test for long-term drug use. Because hair grows slowly (only about 0.5 inches per month), traces of certain drugs can be detected for months. Hair analysis requires more processing time than urine or blood testing. Alcohol 14 Panel Hair Follicle Drug Test $750.00; Does body hair show a longer period of drug use? Now, what if you don’t have hair on your head that is at least an inch and a half? Well, in that case, we can test underarm, leg, or chest hair. Occasionally, we test beards. · just now. 1  If it is a hair FOLLICLE test the drugs will only stay in there for a couple of weeks to a month. If the ENTIRE STRAND (length of the hair from the scalp to the end) is being tested, drugs could stay in there for as much as a year depending on what kind of drugs, the amount used and the time period over which they were used. What Can Affect How Long Do Drugs Stay In Your System? A drug test does not look for the actual drug in your system. It looks for something called a metabolite. When you ingest a substance your body changes (metabolizes) that substance into one or more metabolites. It is these metabolites the drug tests looks to identify. The Varying Detection of Drug Testing Timelines. 1  Single or small doses of any given drug won’t last as long in your system and are not as easily detected. 2  If you have a fast-metabolic rate, you will have a shorter detection of the drug in your body. 3  Your body mass will determine how fast or slow your body metabolises. Query: how long does drugs stay in the hair

Output: Drugs stay in the hair for 90 days.


Input: Consider Input: Martian New Year. On May 5, 2017, Mars passes solar longitude 0 as the Sun crosses the equator on Mars. This is the vernal equinox, and was chosen by planetary scientists as the start of a new year (A Mars year is 687 Earth days). This is year 34 on Mars. (That works today, but eventually we will have more than 24 hours to get this job and others done. A lot more. In a few billion years, a day will last about a month!) Saturn is a giant ball of gas, however. There is no firm surface anywhere in sight. Making things more confusing, Saturn has some of the solar system's fasted winds, up to 1,000 mph. Earth takes 24 hours to complete a day, but Saturn takes 10 hours and 32 minutes. A year on Earth is, obviously, 1 year, while a year on Saturn lasts 30 years. Due to Saturn's tilt and Earth's changing orbital position, Saturn's rings tilt in and out of view over time. Saturn's rings tilt out of view when they are edge-on as viewed from Earth. This is called Saturn's ring plane crossing. Saturn's rings are edge-on to the Sun two times during Saturn's 29.42-year orbit. So if Mars and Earth are side-by-side every 780 days, let's figure out how long it takes for Mars to go around exactly once. We know that in 780 days, the Earth has revolved around the sun twice in 730 days, with 50 days left over. In those 50 days, the earth goes around the sun 50/365 of an orbit. Since Mars and Earth are neck-and-neck in 780 days, Mars must have been lapped in its race with the Earth. They are at the same place on the track (50/365 along it), so Mars must have run 1 (50/365) laps in 780 days. Padalka logged his own 365th day in orbit back in 2004 on what was just his second mission. Now set to fly on his fifth long-duration flight, he will become the new worldwide record holder for the most cumulative time in space when he completes his current mission, topping 900 days. [One-Year Space Station Mission: Full Coverage] How Long Is A Day On Saturn? Date: May 3, 2006 Source: Particle Physics & Astronomy Research Council Summary: Measuring the rotation period of a rocky planet like the Earth is easy, but similar measurements for planets made of gas, such as Saturn, pose problems. Researchers from JPL, Imperial College London and UCLA present new results in this week's Nature (4th May 2006) that may solve the mystery. A: One year on Neptune is equal to around 165 Earth years or 60,190 Earth days, which is the amount of time it takes the planet to complete its orbit around the sun. Days on Neptune last about 16 hours, which is 8 hours less than Earth. 1. Mercury: One year on planet Mercury takes just 87.97 earth days. This means that if you are 15 years old on Earth you would be 62 years old in Mercury years. 2. Venus: It takes 224.7 earth days for Venus to travel once around the sun. If you are 15 years old on Earth, this would make you 24 years old in Venus years. 3. Earth: One year on planet Earth, or one orbit around the sun, takes 365.26 days. 4. The length of one sidereal Earth year is 3.39% the length of one sidereal Saturn year. In other words, the length of one sidereal Saturn year is 29.5. Query: how long is one year one year on saturn in earth years


Output: One year on Saturn in earth years is 30 years.
